AMBROSIA SPECIFICATIONS
- Power Supplies
4 completely separate sets of transformer windings which power
the four main sections of the preamp. These four sections
are moving coil, moving magnet, line, and display and control.
Each section in addition has its own multiple regulators (16
regulators in all).
- Line Amp
3 main inputs (CD, FM, AUX) plus one combo XLR jack that can
be either balanced or unbalanced.
Separate tone controls for each channel, both bass and treble,
with 4 different inflection points each selectable via main
menu.
- World’s most exotic power transformer Triple
shielded with Fe bands plus interlayer grounded shields,
plus complete mumetal wrap, plus complete seamless Fe can.
- Balanced input circuit has an anti-common-mode driver
to pre-vent common mode distortion.
- Discrete power buffers will drive any headphones
known to man. 2 pairs on the front panel. Main outputs are
single ended (2 pairs) and balanced, 2 pairs.
- Complete tape copy and monitor functions for 2 decks.
- Completely separate and dedicated inputs and outputs
for both MC and MM cartridges (as well as through tape functions).
Both phono sections are completely separate each with their
own Power supply regulators.
- Each phono section has its own selectable 20Hz low
cut filter.
- All grounding has been engineered to completely
eliminate any possibilities of grounding interference or ground
loops.
- Interface System
The user interface system in the Ambrosia is all electronic.
There ae no physical switches on controls of any kind in the
signal pth. All functions are 100% microprocessor controlled.
On the font panel there are 5 push button momentary switches
and a main optical shaft encoder. These 6 functions are exactly
dupli-cated on the remote control (supplied). The entire operation
of the system is menu driven which makes functionality a breeze.
Once learned, you’ll never use another preamp without
it.
